Abstract

A cinched parachute is disclosed. In various embodiments, a cinched parachute as disclosed herein includes a canopy comprising one or more sections of canopy material, and a device integrated with the canopy that controls dimensions of the canopy material. For example, in some embodiments the device may be used to control the size of an opening atop the parachute.

First claim

What is claimed is:

1. A cinched parachute, comprising:
a canopy comprising one or more sections of canopy material, wherein a first panel of the canopy is configured to be moved in a first direction and a second panel of the canopy is configured to be moved in a second direction different from the first direction; and
a control device including:
a tether configured to control an amount of air entering the canopy;
a holding device configured to constrain or release the tether, wherein the holding device comprises a brake pad or a clamp; and
a severing device configured to sever the tether, wherein the control device is integrated with the canopy and controls dimensions of the canopy material including widening an opening atop the parachute in response to the first panel and the second panel moving in different directions.

2. The cinched parachute of claim 1 , wherein the control device is threaded through the parachute.

3. The cinched parachute of claim 1 , wherein the control device controls a size of the opening atop the parachute.

4. The cinched parachute of claim 1 , wherein the control device is positioned between tethers of the parachute and the opening atop the parachute.

5. The cinched parachute of claim 1 , wherein the control device is positioned to pull a section of the canopy material into a packed state.

6. The cinched parachute of claim 1 , wherein the control device traverses a casing in the canopy of the parachute.

7. The cinched parachute of claim 1 , wherein at least one end of the tether is secured in the holding device that releases or pulls in the tether.

8. The cinched parachute of claim 1 , wherein the holding device allows the tether to travel in one direction and not in a reverse direction through the holding device.

9. The cinched parachute of claim 8 , wherein the holding device is positioned on or in an object that is tethered to the parachute.

10. The cinched parachute of claim 8 , wherein the holding device is positioned adjacent to the canopy of the parachute.

11. The cinched parachute of claim 1 , wherein the tether is positioned such that the severing device is able to sever the tether.

12. The cinched parachute of claim 1 , wherein the severing device severs the tether to widen the opening within a threshold time.

13. The cinched parachute of claim 1 , wherein the parachute is tethered to an object comprising a timing device.

14. The cinched parachute of claim 13 , wherein the timing device is configured to trigger the holding device or the severing device to perform an action on the tether.

15. The cinched parachute of claim 1 , wherein the parachute is contracted in the event the parachute experiences speed conditions above a threshold and is widened in the event the parachute experiences speed conditions below the threshold.

16. The cinched parachute of claim 1 , wherein the control device is controlled automatically based on sensor information.

17. The cinched parachute of claim 1 , wherein the parachute is tethered to an object comprising sensors.

18. The cinched parachute of claim 1 , wherein the control device comprises one or more additional tethers.

19. A control device comprising:
a tether configured to control an amount of air entering a canopy, wherein the canopy includes one or more sections of canopy material, a first panel of the canopy is configured to be moved in a first direction, and a second panel of the canopy is configured to be moved in a second direction different from the first direction;
a holding device configured to constrain or release the tether, wherein the holding device comprises a brake pad or a clamp; and
a severing device configured to sever the tether, wherein the control device is integrated with the canopy and controls dimensions of the canopy material including widening an opening atop the canopy in response to the first panel and the second panel moving in different directions.
